CATCH-BASIN.

To all whom it may concern:

Be it known that I, CHARLES II. SMITH,

a citizen of the United States, residing at' Boston, county of Suffolk, Commonwealth of Massachusetts, have invented certain new and useful Improvements in Catch-Basins, of which the following Ais a specification.

. This invention relates to apparatus for the disposal of sewage and particularly to means for facilitating the cleaning of catch basins and the like.

My present invention contemplatesa catch basin construction wherein afseparation of` the lliquid and solid substances is positively Y effected-so that the liquid part ofthe sewage is divided and flows out of the catch basin leaving only the solids in the basin.

This is effected by an arrangement of tubular conveyer leading from the inlet opening to an annular chamber in which is arranged a vplurality of symmetrically disposed removable receptacles. The sewage delivered by the conveyer divides among the receptacles, the liquid part flowing out over their tops and being carried away through a suitable outlet opening, and the solids depositing in the receptacles. These receptacles may then be successively removed and emptied by simply removing the fconveyer andthen engaging the receptacles and lifting them out ofthe catch basin. l

The construction andoperation of my device will be more fully disclosed in the speciication which follows.

In the drawings forming part of this specification I have shown a construction which not only clearly illustrates the principles of my invention but is in itself a form found satisfactory in use.

Throughout specification and drawings like reference numerals are correspondingly A q Specification of Letters Patent. *Pgrgnted Spg., 10, 1918, Application filed. April 1Q, 1915.A Serial No. 22,220. I

Removably mounted in the catch basin l below the inlet opening 2 and the manhole p devices 9 projecting laterally from the side 4 wall of the catch basin. If desired, underneath support for' the receptacle receiving structure may be provided, as by the vertical post 17 which rests on the bottom wall ofthe vcatch basin and engages said structure from below. i

The supporting structure for the receptacles 8 may conveniently be 4formed as a spider having an iiiclosing rim 10 and a plurality of radial arms l1. The rim 10 and arms l1 define a symmetrical series of sectorshaped chambers 12 in which the receptacles 8 are removably received, in radialv assembly. If desired, thesupporting member 10 may be made in sections to facilitate its assembly within the ,catch'basirh Each receptacle S below itsv cleared 'poi'- tion 7 has anlexternal flange or bead13 adapted to rest on the arms 1l and horizontal portion of the rim l0. Below the flange 13 each receptacle has a bar 14 connecting may be engaged bya suitable hooked tackleV whereby the receptacle may be lifted out of the catch basin and emptied.

y The rimlO in addition to providing a support for the receptacles forms with the curved under sides of the receptacles 8 an annular inclosing chamber or pocket 15 into which the liquid part of the sewage deposited bythe `conveyer 5 into the receptacles 8 and displaced therefrom by the heavier solids may flow, when the chamber 15 overflows, the liquid passes between the supporting'devices 9 and out through the outlet opening 3 to the sewer. Thefsolid matter delivered bythe conveyer 5 falls to the bottoms of the receptacles 8 and is not discharged Yuntilfthe receptacles are removed and emptied.

not be taken care of by the members 8-10, is provided through a lateral delivery device 16 yin the conveyer 5. If there has been an unusual flow of sewage, as in the case of a freshet, or the like, this overflow backs up in the conveyer 5 until it Yflows out of the lateral exit opening 16 and then down around the rim l and out through the outlet opening 3, to the sewer connection. The

,separately engagedy and removed. and einptied of the solids deposited therein. j

"It'will be observed that the cleared portions 7 lot they receptacles Sfare symmetrically disposed about the center of the spider and that the bottom edgeY of the conveyer is uniformly supported by the cleared portion' o1c eacli receptacle so that the sewage is positively directedinto the receptacles.

As the receptacles fill, the heavier solids dis# .place the liquid part vof thesewageso that the liquid isforced. out over the top edges or" the receptacles into the inclosing chamber 15 and thence to the outlet opening 3.v

lVarious modifications in the formV and construction of my device may obvioiislybe resorted to if within the limits of the appended. claims.' A

What I therefore claim and desire to secure by Letters Patent is: i

l. A catch basin having an inlet and an outlet, a series of receptacles removably supported therein above said outlet, anda conveyer extending from the inlet into and below the top level of said receptacles and having its discharge end disposed in communicating relation to all of said receptacles.

2. A catch basin having an inlet and an outlet, aseries of receptacles removably sup` ported'in said catch basin, and a conveyer extending from said'inlet. and having a dischargev end overlapping all of said receptacles. i

'A catch basin having an inlet and an outlet. a series ofreceptacles removably supported in said catch basin, a supporting member. for said receptacles inclosing the open ends of said receptacles and' adapted to receive the voverliow therefrom, and a conveyer extendingvfrom said inlet to said receptacles' and having a discharge end 'disposed incommunicatiiig relation thereto.

4. A sewage separator' comprisinga pluy rality of receptacles, means for externally supporting said receptacles in radial assembly, said receptacles each having the upper 'edges of their Walls cleared adjacent to the common center, and a conveyer disposed witlrits end overlapping all of said receptacles within said'cleared spaces.

5. A sewage separator comprising a plu- '.ralitywof receptacles, means for externally supportingsaid receptacles in radial asseinbly,.sa1d supporting means defining with Vsaid receptacles an annular liquid trap, and
